About the Role:

As a growth-focused Fullstack Engineer on our team, you will play a central role in driving user acquisition, conversion, and retention through highly performant and visually stunning web experiences. You will collaborate with cross-functional teams—from marketing to sales to product design—to build dynamic pages, run A/B tests, and optimize conversion funnels.

In this role, you’ll design and develop scalable features that enhance the user journey, integrate feedback loops, monitor key metrics, and ensure the reliability of our acquisition funnel. By staying updated on industry trends and focusing on delightful UX, you’ll continuously refine our web properties—ultimately delivering an exceptional experience from first touch through ongoing engagement.

• Design and implement scalable applications, web services, and APIs with a focus on user experience and performance.
• Contribute to our design system and uphold industry-leading UX standards (e.g., interactions, micro-animations, layout consistency).
• Continuously improve engineering processes, tools, and systems to scale the codebase and team productivity.
• Troubleshoot and fix bugs, delivering quick, high-quality resolutions.
• Write technical documents and maintain internal tools to empower other teams.
• Review and provide feedback on contributions from other engineers.
• Identify bottlenecks and optimize for conversion, speed, and reliability across the funnel.
• Critically think about foundational areas of the Vercel application to ensure ease of maintenance and future extensibility.

About You:

• Strong proficiency in Next.js and familiarity with modern frontend frameworks.
• Full stack experience (comfortable designing or consuming APIs and working with various services).
• Deep understanding of SEO principles and best practices—especially around performance, accessibility, and search optimization.
• Proven knowledge of A/B testing concepts and conversion rate optimization.
• Stellar cross-functional communication skills—you can work effectively with marketing, design, and product to reach shared goals.
• Eye for good user experiences and a knack for “getting the visuals right.”
• Desire to work in a fast-paced environment, continuously grow, and master your craft.

• Have familiarity with the Vercel platform.
• Comfortable using Tailwind CSS.
• Background in web design or interest in design systems.
